  SAP Error Message:
  
  WP303 - The number of IDoc & is not in line with specifications
  
  Cause:
  This error occurs when the number of IDocs (Intermediate Documents) generated or expected does not match the predefined or configured specifications in the system. Specifically, during processes like IDoc generation, processing, or posting, the system expects a certain number of IDocs based on the configuration or the business scenario, but the actual number differs.
  Common scenarios causing WP303 include:
  
  Mismatch in the number of IDocs expected vs. generated during outbound processing.
  Incorrect partner profile or message type configuration leading to unexpected IDoc counts.
  Errors in the segment or message type definitions causing incomplete or extra IDocs.
  Custom enhancements or user exits that alter the number of IDocs without updating the specifications.
  Batch or mass processing jobs where the count of IDocs processed is inconsistent.
  
  
  Solution:
  To resolve the WP303 error, follow these steps:
  
  
  Check Partner Profile Configuration:
  
  Use transaction WE20 to verify the partner profile settings.
  Ensure the message type and the number of IDocs expected are correctly configured.
  
  
  
  Verify Message Type and IDoc Type:
  
  Use WE30 to check the IDoc type and segments.
  Confirm that the message type corresponds correctly to the IDoc type.
  
  
  
  Review the Process Generating IDocs:
  
  Identify the process or transaction that triggers the IDoc creation.
  Check if any custom code or user exits modify the number of IDocs.
  Debug or trace the IDoc generation to see why the count differs.
  
  
  
  Check Batch Jobs or Mass Processing:
  
  If the error occurs during batch processing, verify the job logs.
  Ensure that the input data and selection criteria are consistent.
  
  
  
  Reprocess or Recreate IDocs:
  
  If IDocs are incomplete or corrupted, consider deleting and regenerating them.
  Use WE19 for test IDoc processing.
  
  
  
  Consult SAP Notes:
  
  Search for relevant SAP Notes on the SAP Support Portal using the error message or code.
  Sometimes, patches or corrections are available for known issues.
